Hacktool.FxScanner Information and Removal.

A Potentially Dangerous Tool is an application that is not necessarily harmful if properly installed by the user or administrator of the PC, but which could be harmful or disruptive to the user, PC, or network if deployed by unauthorized parties for potentially malicious purposes.

Low risks should not harm your machine or compromise your privacy and security unless they have been installed without your knowledge and consent. A low risk may be a program, network tool, or system utility that you knowingly and deliberately installed and that you wish to keep. Although some low risk programs may track online habits -- as provided for in a privacy policy or End User License Agreement (EULA) -- or display advertising within the applications themselves, these programs have only vague, minimal or negligible effects on your privacy. Low risks may also be cookies, which can be used to track your online activities, though without identifying you personally.
